From: Impact of insulin therapy on the mortality of acute heart failure patients with diabetes mellitus
Subgroup analysis on the association between diabetes mellitus treatment type and overall mortality. Subgroup analyses on the association between diabetes mellitus treatment type and overall mortality according to age, sex, etiology of heart failure, left ventricular ejection fraction, glycosylated hemoglobin level, natriuretic peptide level, and NYHA class after double adjustment of weighted Cox proportional hazard regression model. A Insulin-only group versus oral hypoglycemic agent (OHA)-only group (reference). B All-insulin group versus OHA-only group. Low BNP and high BNP were defined as BNP < 500 pg/mL and NT-proBNP < 1000 pg/mL, and BNP ≥ 500 pg/mL or NT-proBNP ≥ 1000 pg/mL, respectively
